Land pollution causes the land’s productivity and potential to decline to such a level that the purpose of utilising lands for building infrastructures, housings, services, agriculture, forestry and many more for the development of human being are no longer achievable (Prabhakar, 2012). Land pollution are resulted by some sources which are deforestation, mining and construction activities. Deforestation appears to be the major concern as once the land is converted into dry lands, it can hardly be made fertile again. Those areas inevitably end up as waste lands. Mining requires the removal of topsoil containing valuable organic matters.
As there were news hitting news channel about increase in amount of pollution of land. Some of the effects that land pollution leaves behind are obvious ones, such as unsightly piles of garbage, landfills and loss of environments surrounding new construction. Many of the worst effects are actually less obvious to the eye. Chemical Effects on Life One of the biggest threats to the eco-system caused by land pollution is chemical contamination. Plastics, toxins in wastes like anti-freeze and other chemicals seep into the ground where they remain.
Soil pollution occurs due to the presence of toxic chemicals in the soil that can adversely affect the natural soil environment. Soil pollution is said to occur when the levels of contaminants in the soil exceed the levels that should naturally be present. What causes soil pollution? Soil pollution can be caused by man-made pollutants and natural pollutant. Man-made soil pollution usually caused by agricultural activities, construction activities, mining activities and waste disposal.
‘Agricultural pollution’ is an umbrella term used to describe the sources of wastes, emissions, and discharges arising from farming activities, and includes, but is not limited to: livestock and livestock manure, poultry litter, chemical fertilizers, chemical pesticides, sediment, agro-chemicals, organic containments, heavy metals, and general farm procedures. This form of pollution greatly affects bodies of water across the globe. According to 2015 estimates from the Bay Program, “agriculture contributes 42 percent of the nitrogen, 55 percent of the phosphorus and 60 percent of the sediment entering the Bay,” making it the largest source of sediment and nutrient pollution in the Chesapeake Bay. Nitrogen and phosphorus are the two most common
Firstly the activities which may cause land based pollution are within the territorial sovereignty of each state, and such activities are closely bound up with crucial national programmes for economic, industrial and social development of those countries. Hence states are often reluctant to approve any attempts at restricting their economic developments by legally binding instrument. Secondly the regulation of land based pollution is more complexed than that of pollution from other sources. Because in case of land based pollution sources and substances are difficult to identify Land based sources are variable in their nature over time and each source requires different measures to prevent environmental damage. Thirdly, the ocean environment is not homogeneous.
Some effects of land pollution are the unsightly piles of garbage, landfills and loss of environments surrounding new construction. Chemical contamination to the land are severe threats to the eco-system. Items like plastics, toxins in wastes like anti-freeze and other chemicals get into the ground and remain there. Most chemical are non-biodegradable or cannot break down, or sometimes they break down into smaller chemicals which are still harmful to the land. The particles poison the ground.
We should promote such a farming where there is no harm to the environment. Today, in most industrial agriculture, there is excessive use of chemical fertilizer and insecticides. Though many types of pollutants are responsible for destroying the fertility of the land, excessive use of chemical fertilizers is one of the main reasons. In chemical fertilizers, phosphate, nitrogen and other chemicals are polluting the environment and groundwater resources of land. The most dangerous pollutants are bioactive chemicals, due to which the micro-organisms of climate and soil are being destroyed resulting in decreased quality of soil.
For example, roundup, an extremely common herbicide used in agriculture, is highly toxic to fish and amphibians. The National Coalition for Pesticide-Free Lawns says, "Of 30 commonly used lawn pesticides, 19 are linked with cancer or carcinogencity, 13 are linked with birth defects, 21 with reproductive effects, 26 with liver or kidney damage, 15 with neurotoxicity, and 11 with disruption of the endocrine
The drainagewater contains heavy metals in addition to biological contaminations so care has to be taken to avoid this water. Land/ Solid waste Pollution- the main cause of environmental pollution is improper management of solid waste. The causes of Land pollution are: waste disposal, mining, urbanization, agriculture chemical, atmospheric deposition, soil erosion. The adverse effect of pollution is global warming-refers to the general increase in the earth’s average temperature, which causes changes in climate patterns across the globe. The earth’s average temperature has been increasing over the last century.
France-3 Minister for Energy Introduction The pollution of the air is a major challenge that has a negative impact on everyone. There are various types of pollutants. Besides, the many ways to group pollutants, for instance, pollutants can be classified according to the distance in which their adverse effects are felt. Basing on this classification, there are pollutants that affect the global and local ecology. Some of the pollutants that affect local ecology include; emission of carbon (II) dioxide from cars, cigarette smoke.
